SAT Excel Online Course

My brother took the SAT Excel prep course in Fremont a couple of years ago and he really liked it. It helped him increase his score from a 2100 to a 2360. We don’t live in CA anymore so I was looking into the online (http://www.exceltest.com/page/sat_online_course) Excel course. Has anyone taken it? How much does it help? Right now, I’m at a 2180. I’m aiming for a perfect 2400.
